Abstract (en)
A scanner including a plastic focusing lens and thermal compensation element, integrally formed with the asphere or comprising a separate element, to replace the existing glass laser diode focusing lens. The combined optical system is thereby configured to provide overall temperature compensation for the system with reduced cost and improved performance. <IMAGE>
